Abstract

PROBLEM TO BE SOLVED: To suppress inclination and fall of a through column in an earthquake or a typhoon by tightening it with a bolt after the lower end of the wooden through column is inserted in the cylindrical frame of a column leg fitting. SOLUTION: A column leg fitting 1 vertically integrating a cylindrical frame 4 whose upper part is opened on a base plate is mounted on a continuous footing (a) burying an anchor bolt 20 and tightened and fixed by the anchor bolt 20. Next, after the lower end 31 of a wooden through column 30 is inserted in the cylindrical frame 4, a bolt 37 is inserted in the cylindrical frame 4 and the wooden through column 30 from the horizontal direction to be tightened and the wooden through column 30 is fixed on the column leg fitting 1. In this case, a packing material is preferably mounted between the upper face of the base plate 2 and the bottom face of the lower end 31 of the wooden through column 30. Thereby strong resistant force is produced on the through column 30 for external force such as front and rear, right and left and upper and lower vibration or the like and the inclination and fall of the through column 30 in an earthquake or a typhoon can be suppressed.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a column base metal installed on a cloth foundation in a wooden construction method and a method for fixing a wooden through column using the column base metal.

[0002]

2. Description of the Related Art As shown in FIG.
Place the base b on the concrete cloth base a
The base b is firmly fastened and fixed with an anchor bolt c embedded in the base, and the lower end of the through column p is inserted into a tenon provided in the base b, and the base b and the through column p have a thickness of about 2.3 mm. Work is performed to tightly connect the two by applying nails to the metal fittings d, or nailing them together. In addition, a method of fixing a vertically long L-shaped drawing hardware on a base side with a bolt with a washer or an anchor bolt and attaching a standing piece of the hardware to one side of the through pillar by nailing to fix the through pillar to the base is also generally used. Is being done.

[0003]

In the above-mentioned conventional method of fixing the through column to the base, when the house shakes due to an earthquake or a typhoon, the connecting portion between the through column / tube column and the base is loosened and the house collapses. It is said that they may suffer such damage. According to the damage survey results of the "Great Hanshin-Awaji Earthquake" that occurred in January 1995, poor connection at joints such as joints and connections was one of the causes of damage to wooden houses.
One seems to have been pointed out. From this,
It is desirable for through pillars, which are considered to be particularly important in wooden construction, to have a seismic structure that can be sufficiently connected to a cloth foundation or a base and sufficiently withstand an earthquake or a typhoon.

[0004] It is an object of the present invention to provide a column base metal member having improved seismic resistance by firmly connecting a through column to a cloth foundation, and a method of fixing a wooden through column using the column base metal member.

[0005]

According to one aspect of the present invention, there is provided a column base metal fitting having a through hole through which a shaft portion of an anchor bolt buried in a cloth foundation is passed, the upper part of which is provided on a base. The open tubular frame is integrally formed in the vertical direction, and a bolt hole for appropriately passing a bolt for fixing a lower end portion of the wooden through pillar is provided on a side surface of the tubular frame.

In order to achieve the same object, according to a second aspect of the present invention, there is provided a method of fixing a woody pillar, wherein an anchor bolt is buried in a column base metal having a vertically open cylindrical frame integrally formed on a substrate. After being placed on the cloth base and tightened and fixed by the anchor bolts, the lower end portion of the wooden through pillar is inserted into the tubular frame, and then the bolt is passed through the tubular frame and the wooden through column from the horizontal direction to be tightened. The through column is fixed to the column base hardware.

[0007] In the method for fixing a wooden through pillar according to a second aspect, it is preferable that a packing material is attached between an upper surface of the substrate and a bottom surface of a lower end portion of the wooden through pillar.

[0008]

According to the present invention, the column base hardware is tightly fixed on the cloth foundation by means of anchor bolts, and the wooden through pillar is tightly connected to the cylindrical frame through bolts while being inserted into the cylindrical frame. Thus, since strong resistance to external forces such as front-back, left-right, and up-down vibrations is generated in the through pillar, the tilting action of the through pillar during an earthquake or typhoon is suppressed, and detachment from the fabric foundation is prevented.

Further, when a packing material is mounted between the upper surface of the substrate and the bottom surface of the lower end of the through pillar, the relief work area for the projecting portion of the anchor bolt of the through pillar can be reduced. And the strength of the through column does not decrease.

However, according to the pillar base metal fitting and the method for fixing a wooden through pillar using the pillar base hardware, the through pillar can be firmly connected to the cloth foundation via the pillar base hardware, so that the earthquake resistance is improved. .

[0011]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a pillar base, FIG. 2 is a perspective view of a packing material, and FIG. 3 is a vertical sectional side view for explaining a method of fixing a wooden through pillar using the pillar base.

As shown in FIG. 1, the pedestal hardware 1 includes 9-1.
A through hole 3 for passing a shaft portion of an anchor bolt 20 is provided in the center of a rectangular substrate 2 having a thickness of about 2 mm, and a rectangular cylindrical frame 4 whose upper part is opened is placed on the upper surface 2 a of the substrate 2. It is formed integrally by welding or the like in the vertical direction. A pair of bolt holes 6 and 7 for passing bolts 36 and 37 for fixing the wooden pillar 30 in an orthogonal shape are provided on the side surface of the cylindrical frame 4 near the opening 5.

Reference numeral 10 denotes a rectangular packing material made of a hard plastic, and a large-diameter stepped hole 11 is formed at a central position thereof. The packing material 10 is mounted between the upper surface 2 a of the base 2 of the pillar base 1 and the bottom surface 32 of the lower end of the wooden through pillar 30. It should be noted that the use of the packing material 10 makes it possible to reduce the processing area of the recess 33 with respect to the protruding portion of the anchor bolt 20 of the through column 30, but it is not always necessary to use this.

Next, a method of fixing the wooden through pillar 30 by using the above-mentioned pillar base hardware 1 will be described. As shown in FIG. 3, the column base metal 1 is placed on a cloth foundation a in which an anchor bolt 20 is embedded, the anchor bolt 20 is passed through the through hole 3, a washer 21 is fitted, and then tightened and fixed with a nut 22. Apply. Next, the stepped hole 11 of the packing material 10 is fitted into the projecting portion of the shaft portion of the anchor bolt 20, and the packing material 10
Is set on the upper surface 2 a of the substrate 2.

After inserting the lower end 31 of the wooden through pillar 30 into the tubular frame 4 of the pillar base 1, the tubular frame 4 is inserted into the tubular frame 4.
Bolt holes 6 and 7 and through holes 34 and 35
And tighten the bolts 36 and 37 from the horizontal direction. Thus, the wooden through pillar 30 is securely fixed to the pillar base 1.

According to the above-mentioned pillar base metal fitting and the method of fixing the wooden through pillar using the pillar base hardware, the wooden through pillar can be firmly connected to the cloth foundation through the pillar base metal, so that the earthquake resistance is remarkably improved. .
